SPECIFICATION forming part of Letters Patent No. 284,548, dated September 4, 188.3.

` Appiicanon men my 25, 1883.' (No model.) 'A

T @ZZ whom it may concern,.-

Be it known that I, WALTER 1B. GwYN, av citizen' of the UnitedStates, residing at Asheville, in the county of Buncombe and `State of North Carolina, have invented new and use- Lful Improvements in Billiard-Cue Trimmers, of which the following is a specification.

My invention relates to billiardcue trimmers, and has for its object to provide a simple device for trimming and shaping the leather tip of a cue to preserve a true uniform curva-4 ture of the same. l q

To this end my invention consists in a block composed of wood, metal, composition, or other suitable material, and provided with a series of chambers, each having a concave bottom covered with sandpaperor emery-cloth,`the

l curvature of each bottom being graduated throughout the series in accordance with a fixed standard, and the scale of curvature beingV indicated by any appropriate symbol, whereby a cue-tip may be trimmed to any convexity desired by a player.

`Referring to the drawings which accompany and form part of this specification, Figure l is a perspective view illustrating my invention. Fig. 2 is a transverse section of Fig. l in the line I l.

IA in said drawings indicates ablock, which may be made of wood, ,metal,composition, or any other suitable material, and of any desired form. `Within the body of this block are formed recesses or chambers B, each of such size as to admit the tip ofabilliard-cue. The bottom of each chamber isof concave form, the degree of concavity varying throughout the series,"from the lowest, as at No. l, to the highest degree, as at No. 6. The concave bottom of each chamber B is coveredwith any suitable abradingmaterial, a-such as sandpaper or `emery-clothwhicl1 may be fastened in place by, glue or cement, and be removed when worn out and replaced by new material. In order to economize space, the chambers B may be formed upon both si'des of the block A,as shown `in Fig. 2, and the arrangement 'as regardsthe relative concavity maybe such that the scale `of concavity shall increase from one to the other `in regularbrder, (indicated by` a number or other symboh) and, if desired, the degree of curvature of each may also be yshown by a line representing the same, delineated upon the block, or upon a tag which is fastened to the block near eachV chamber.

It is well known by all billiard-players that 5 5 the curvature or conveXity of the cue-tip is a tomed to use a tip having a given degree of 65 conveXity cannot play' successfully with any other. Moreover, for reasons already stated, the tip requiresto "be frequently trimmed in order to true f7 it, giving it an equal conveXity upon all sides of its center. 7o

In using my invention the end of the cue is introduced into one ofthe chambers B, having its bottom concaved to the required degree, and the cue is revolved in the block, or the block may be turned upon the cue. The sandpaper or other abrading material quickly trims the tip off to the desired degree of conveXity, giving a true curvature at every point, besides imparting a fresh, clean surface also, lwhich takes the chalk readily. i y 8o If desired, the' chambers B may be made of differentsizes, so that they will support the cue and hold its end squarely against the bottom while being trimmed. `This is'not essential, however, as every experienced player will find no difficulty in using the trimmingblock without it.

In manufacturing this device I have found it advantageous to form the chambers B by casting or` molding, as I am able to obtain a 9o more accurate curvature ofthe bottom of each in that manner.

Having thus described my invention, what 4I claim isl. A tip-trimmer for billiardcues, consisting of a block having a series of trimmingchambers formed therein, the bottoms thereof being concaved upon a regularly-increasing scale of curvature, andcovered with any suitable abrad` ing material, substantially as described. rco

2. As an improved article of manufacture, thel cue trimmer described, consisting of a block, IA, having aseries of chambers7 B, each having a bottom of a given curvature covered with abrading material a, suitable symbols being applied to the' block near each chamber 5- to indicate the relative concavity of its bottom,

substantially as described.

3. The combination, with the block A, having chambers B,Withb0ttoms of varying curvature7 of abradingmaterial a, covering the bot- Io tom of said chambers7 and glue or similar material for securing the material in place, whereby it may be removed and freshmaterial substituted, as set forth. n

In testimony whereof I have hereunto set my hand in the ,presence of tWo subscribing Wit- 15 nesses` i n WALTER B. GWYN. Witnesses: v
